The poster gives fans a good look at Chris Evans in his Captain America costume, with the looming Red Skull (Hugo Weaving) behind him. By Cap's shoulder is his love interest, Agent Peggy Carter (Hayley Atwell), and to his other side is his Colonel Phillips (Tommy Lee Jones), who is at first skeptical of Steve Rogers entering the Super Soldier program. To Cap's side is his sidekick Bucky Barnes (Sebastian Stan) as well as the members of Cap's "Howling Commandos" — Timothy "Dum Dum" Dugan (Neal McDonough), Gabriel Jones (Derek Luke) and Montgomery Farnsworth (J.J. Field) on the right, and Jim Morita (Kenneth Choi) and Jacques Dernier (Bruno Ricci) on the left. See a high-res version here.

The first preview clip comes from MTV, with Colonel Phillips expressing his doubt about Steve Rogers' inclusion in the Super Soldier program to Dr. Abraham Erskine(Stanley Tucci), and offers a test to the recruits.

The second clip comes from Yahoo, and shows Rogers in the midst of his transformation into Captain America.

The third clip comes from Moviefone, and shows Howard Stark (Dominic Cooper), later the father to Tony Stark, a.k.a. Iron Man, introducing Cap to his iconic shield.

The final preview clip comes from IGN and shows what everyone wants to see: Cap in action, tearing through several members of HYDRA.
